STEAM JOINT. 7

Application filed April 1,

The invention relates to improvements in joints for use in piping and has reference more particularly to such joints as those employed in connection with the steam chests for the vertically movable pressing heads of garment presses.

The object of the invention is to provide a joint of exceptionally simple and inexpensive construction, yet one which will be highly eflicient and desirable for the purpose of feeding steam to the chest and exhausting the steam therefrom.

lVith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.

Figure 1 is the top plan view showing the application of the invention to a garment press.

Figure 2 is a sectional view as indicated by line 22 of Figure 1, illustrating the joint in side elevation.

Figure 3 is a horizontal sectional view on line 33 of Figure 2.

The drawing above briefly described, illustrates the preferred form of construction and while such construction will be hereinafter rather specifically described, it is to be understood that within the scope of the invention as claimed, variations may be made.

The numeral 4 designates an elbow having an outer relatively large passage 5 opening through its ends and an inner comparatively small passage 6. At one of its ends, this elbow is provided with an outer relatively large tube 7 which projects rigidly from said end and communicates with one'end of the passage 5, and within said outer tube 7 is a relatively small inner tube 8 which also projects rigidly from the elbow, the inner end of said tube 8 being in communication with one end of the inner passage 6, while the outer end of said tube 8 projects beyond the tube 7. In the present showing, the tubes 7 and 8 have threaded connections 9 and 10 respectively, with the elbow 4, and the outer end of said tube 7 is threaded as indicated at 11, to be tapped into an opening in the steam chest 12 of the movable presser head of a garment press, such a press being indicated in a general way in Figure 1.

1926. Serial No. 99.115.

. An outer relatively large tube 13 and an inner comparatively small tube 14, project rigidly from the end of the elbow 4, remote from the tubes 7 and 8, said tubes 13 and 14 communicating respectively with the pas sages 5 and 6. The outer sleeve 13 is pref erably though not necessarily integral with the elbow 4 and the tube 14 is by preference threaded into said elbow as indicated at 15, and the outer end of this tube ;14 projects beyond the tube 13.

An elongated, substantially cylindrical body 16 is provided with a cylindrical bore 17 opening through one of its ends and turnably receiving the tube 13, and said body 16 is formed with a steam inlet nipple 18 whose bore 19 is axially alined with the first named bore 17, the inner end 20 of said bore 19 being counterbored and turnably receiving the end of the inner tube 14 which projects beyond the outer tube 13. Leading laterally from the bore 17, is a-steam exhaust port 21 which is preferably threaded for engagement with an exhaust pipe 22, and it will be seen that the nipple 13 is shown provided with screw threads b means of which it may be readily couple to the steam supply pipe 23.

Means are provided for anchoring the body 16 to the frame of the garment press. In the present showing, a flan e 24'is integral with and surrounds this ody, and a nut 25 is threaded upon said body for coaction with this flange in tightly securing the body in an opening in an appropriate bracket 26 which is secured by a bolt or the like 27 to the press frame. The threads 28 of the body 16, engaged by the nut 25, are also instrumental in providing for the attachment and adjustment of a packing gland 29, whose packing 30 prevents any leakage of steam between the body 16 and the sleeve 13.

By the novel construction shown and described, steam may readily enter the chest 12 regardless of the vertical position to which the latter ismoved, the steam passing through the bore 19, through the tube 14, through the passage 6 and through the tube 8, into said chest. Exhaust of steam from this chest takes place through the tube 7, the passage 5, the tube 13, the bore 17 and the port 21.

On account of the advantages existing for the exact construction herein d sclosed,

it is by preference followed. However, as a above stated, variations may be made within the scope of the invention as. claimed.

I claim:

1. A connection of the class described comprising an elbow having inner and outer relatively small and large passages, a tube projecting rigidly from one end of the elbow and communicating at its inner end with said inner passage, said one end of said elbow forming an exhaust fluid inlet around said tube and being adapted for connection with a chzmher, an outer relatively large tube and an inner compara tively small tube disposed in spaced concentrio relation and both projecting rigidly frointhe other end of the elbow, the inner endlQ said inner tube being in COllllllLlIl-l cation with said inner passage while the Outer end ofthis tube projects. beyond the outer end ot' said outer tube, a coupling bodjyhaving t cylindrical bore turna-bly receiving said outertube, said body having a fluid inlet nipple whose bore is axially alined with the first named bore and is counter bored at itsinner eno and to. turnably receive the projecting end at said inner U, c, and a" fluid outlet from said first named bore.

2. A structure specified in elai n'i 1; said body having a. peripheral flangeadap-ted tov abut one side of a support, said body beingthreaded substantially troin said flange to the end of the body adjacent; said elbow, and a nut and stufling box threaded upon said body, said nut being cooperable with said flangeto secure the body to the support, said stuffing bozr servingto prevent leakage of fluid between said outer tube and said body.

3. A connection of the class described comprising an elbow having inner and outer relatively small and large passages, two straight relatively large outer tubes projecting rigidly from the ends of said elbow' and communicating withthe ends of said outer passage, two straight relatively small inner tubes within said outer tubes andalso projecting rigidly from said lbow, the inner ends of said inner tubes being in coi'nn'iunication with the ends of said inner passage hile the outer ends of said inner tubes project beyond said outer tubes, an elongated cylindrical body havstraight bore which turnably receives one of said outer tubes, said body having a. fluid inlet nipple whose bore is axially alined with the first named bore, said nipple bore beingcounterbored at its inner end and turnably receiving the end of the inner tube which projects beyond said one outer tube, and a fluid outlet from the first named bore.

4-:. A structiu'e specified in claim 3; said body being externally threaded from its open end to. a point between its ends and having an outstanding annular flange at the inner end of the screw threaded portion, a nut. threaded upon said body and cooperable with said flange to secure the body to its support, and a stuiii ng box threaded upon the open end of said body'toprevent leakage of fluid between the body and said one outer tube.

In testimony whereof I have hereunto aiiixed lllyi signature.
